(vi) Which one amongst the following rivers flows through a rift valley?

Mahanadi

Krishna

Tungabhadra

Tapi

Answer: (d)

Explanation:

A rift valley is a linear-shaped lowland between several highlands or mountain ranges which is created by the action of a geologic rift or fault. Tapi flows through the rift valley.

Most of the major rivers of the Peninsula such as the Mahanadi, the Godavari, the Krishna and the Kaveri flow eastwards and drain into the Bay of Bengal. These rivers make deltas at their mouths. The Narmada and the Tapi are the only long rivers, which flow west and make estuaries. The drainage basins of the peninsular rivers are comparatively small in size.

The Narmada Basin

The Narmada rises in the Amarkantak hills in Madhya Pradesh. It flows towards the west in a rift valley formed due to faulting. The Narmada basin covers parts of Madhya Pradesh and Gujarat.

The Tapi Basin

The Tapi rises in the Satpura ranges, in the Betul district of Madhya Pradesh. It has a rift valley parallel to the Narmada. Its basin covers parts of Madhya Pradesh, Gujarat and Maharashtra. The coastal plains between Western Ghats and the Arabian Sea are very narrow. Hence, the coastal rivers like Tapi are short

The Godavari Basin

The Godavari is the largest Peninsular river draining from slopes of the Western Ghats in the Nasik district of Maharashtra. Its length is about 1500 km draining into the Bay of Bengal. Among the peninsular rivers it has a largest drainage basin covering parts of Maharashtra (about 50 per cent of the basin area lies in Maharashtra), Madhya Pradesh, Odisha and Andhra Pradesh. Because of its length and the area it covers, it is also known as the ‘Dakshin Ganga’.

The Mahanadi Basin

The Mahanadi rises in the highlands of Chhattisgarh and flows through Odisha to reach the Bay of Bengal. The length of the river is about 860 km. Its drainage basin is shared by Maharashtra, Chhattisgarh, Jharkhand, and Odisha.

The Krishna Basin

Rising from a spring near Mahabaleshwar, the Krishna flows for about 1400 km and reaches the Bay of Bengal. Its drainage basin lies in Maharasthra, Karnataka and Andhra Pradesh.

The Kaveri Basin

The Kaveri rises in the Brahmagri range of the Western Ghats and reaches the Bay of Bengal in south of Cuddalore, in Tamil Nadu. Total length of the river is about 760 km. Its basin drains parts of Karnataka, Kerala and Tamil Nadu. It makes the second biggest waterfall in India, known as Sivasamudram which also produces hydroelectric power.
